2001 APR 11 - (NewsRx.com & NewsRx.net) --
When it strikes cows, pigs, and other livestock, foot-and-mouth disease (FMD) rapidly threatens financial disaster for farmers and, potentially, for entire economies.
Effective vaccines have been available for decades, but practical concerns have limited their use.
A news article in the March 23, 2001, issue of Science examined current prevention, detection, and research efforts to make FMD vaccines more practical.
The European Union banned the vaccines in 1992 because vaccinated animals produce the same antibodies as infected livestock, making it impossible to determine when animals are sick. Since immediate detection is crucial to contain the spread of FMD, countries such as the United States and Japan had banned vaccinated animals, which put pressure on the European Union.
Now, some farmers and politicians argue that vaccinating should begin anew.
"One of the things that could end the current impasse," the Science news report states, "is a test that would separate vaccinated from infected animals."
